The document discusses testing capabilities for IBM Integration Bus (IIB) v10 and Rational Integration Tester. It provides an overview of the IIB v10 Flow Exerciser for testing message flows, transformations, and error handling. It then discusses Rational Integration Tester and how it can be used to implement stubs, create test suites, and enable continuous integration testing. The document concludes with a demo of these capabilities.

3. Introduction

4. Scope of testing
• Applications, Services, Libraries using a variety of transports, formats
and subflows
• Unit testing – how big/small is a unit?
• Message transformation
• Message routing
• Subflows
• System testing – what exactly constitutes the system?
• The system is the Message Flow
• System integration testing
• End-to-end interactions

6. IIB v10 Flow Exerciser
• Introducing the flow exerciser
• Save messages
• Trace path through flow
• Inject messages
• Supported nodes
• MQInput, HTTPInput, SOAPInput
• Use for testing of
• Subflows

Integrations, data
and business logic
Only one-tenth of an iceberg is above water
Traditional UI testing
Automated Integration Testing and
Service Virtualization
The majority of risk in modern systems is
seldom tested as it is unseen.

9. Today, integration of enterprise applications still
follow the “big-bang” approach …
• Integration amongst different components of the enterprise application occur at the end of a
milestone in a “big-bang”
• Difficult to continuously integrate and deploy across different technology stacks and varying
delivery schedules. Very hard for different teams to collaborate together on interim builds inside a
milestone

10. Tests can bypass the UI and
execute beneath the iceberg.
Test while your system is being
built and at an accelerated rate.
Much greater coverage = much
greater confidence
Introduces the concept of testing side effects.
Validate the contents of message queues, log files
and databases as well as simple inputs/outputs.

11. The Continuous Testing Solution: RTW, RPTS, RTVS
• IBM Rational Test Workbench
– Enable functional, performance and integration testing
throughout your project lifecycle
– With a scriptless, wizard-driven test authoring
environment and support for more than 70 technologies
and protocols
• IBM Rational Performance Test Server
– Save time and effort by reusing your functional integration
tests for performance testing
– Combine your tests to model real-world scenarios and
assess the impact of load on your integrated
infrastructure.
• IBM Rational Test Virtualization Server
– Model real system behavior to eliminate test
dependencies and simulate production,
– Accelerate testing and reduce the setup and
infrastructure costs of traditional testing environments.

12. The bottom line
Using IBM’s test automation and
virtualization can eliminate long
back-end test cycles, increase
quality, and lower risk.
Test early and continuously with virtualization
•Verify and validate the
technical solution for a
business change without
waiting for the complete
technical solution to be
built.
Test integrations
•Most of the risk of business
change lies at the
integration layer and
WebSphere solutions need to
be tested below the UI.
•Verify side effects such as
database writes or log file
updates for greater
confidence.
Test performance
•Verify scalability after
upgrading or migrating to the
WebSphere platform.
•Be confident before you add

Integration Testing and Service
Virtualization can significantly de-
risk the migration and reduce the
time required.
Development/test teams can
build against virtual services and
test early and test continuously
using messages captured from
the real systems.
Exception/edge case testing is
much easier to do.
RTW understands a wide range
of technologies and messaging
protocols (including DFDL)
making it well-aligned to IIB
users
Most Orchestration Engines have their own proprietary runtime (unlike JEE) which means migration between vendors
involves risk as development is required. Test environments are expensive and it is extremely difficult to fault-find in an
environment with many moving parts
Example Scenario:
